An architect for a golf course wants to plan a sand trap that passes between a tree and a cart path. Using these as the focus and directrix, how can the architect plan a parabolic sand trap that will be equidistant from the tree and the cart path at all times? Describe your method in full sentences.
sometimes these questions are poorly worded, so im trying to get it

A parabola is a locus of points equidistant from a point and a line.
The point here is the focus and the line here is the directrix.
find the focal length, it is half the perpendicular distance from the focus to the directrix.. then assume the vertex is at the origin then the equation is \[x^2 = 4ay\]
@SolomonZelman can you help?
|dw:1417977932136:dw| or using 2 tape measures... 1 from the focus(tree) and 1 thatis perpendicular from the directrix(cart path), mark a series of points that are equidistant that's a property of the points that make a parabola... |dw:1417978116274:dw|
